  • How much does the U.S. spend to treat different diseases?

    Feature

    This slideshow looks at how much the United States spends to treat specific diseases and tracks spending growth over time, using data from the Bureau of Economic Analysis Health Care Satellite Account. The analysis shows that three disease categories -- ill-defined, musculoskeletal and circulatory conditions -- account for about a third of medical services spending growth in the United States from 2000 to 2010.

    Health of the Healthcare System is a diagnostic look at the state of our healthcare system. How does the U.S. healthcare system compare to health systems of other high-income countries, and how has it fared over time? Kaiser Health News and former-NPR reporter, Julie Rovner, takes us through a check-up of our system by assessing four key areas: how healthy we are, the quality of care we receive, how much it costs, and how accessible it is.

  • Assessing the Performance of the U.S. Health System

    Issue Brief

    Health spending growth has consistently outpaced U.S. economic growth and is higher than medical spending in other wealthy countries. Despite spending more, the United States doesn't have better health outcome in terms of life expectancy, mortality rates and other measures. This brief provides an overview of trends in health costs and the performance of the U.S. health system, including comparisons to countries from the Organisation for Economic Co-operation and Development (OECD). The brief charts growth in the nation's per capita health spending along with the recent slowdown, touching on the roles of expanded Medicaid eligibility, increases in Medicare beneficiaries and the Affordable Care Act (ACA). Additionally, it discusses the health system's effectiveness and capacity to provide services, including the accessibility and affordability of care.
